SUMMARY

Stoke's Law describes the settling velocity of spherical particles in a fluid, which is crucial for understanding the hydrometer test. This law states that the velocity of a particle is directly proportional to the square of its radius and the difference in density between the particle and the fluid. In hydrometer tests, Stoke's Law is applied to determine the specific gravity of liquids by measuring the depth to which a hydrometer sinks. Accurate application of this principle allows for precise measurements in various scientific and industrial contexts.
